cAncULA'rING GAME.

Application led January 15, 1923. Serial No. 612,677.

To all whom 'it may concern Be it known that I, AGNES L. JOYCE, acitizen of the United States, and a resident of Bronx County, in thecity and State of New York, have invented a new and useful CalculatingGame, of which the following is a complete specification.

My invention relates to card games and utilizes the fact thatcomputation, is composed entirely of numbers and operative symbols, and.that various combinations of these numbers and symbols representmathematical operations.

To this end I have'made a set of' cards, all of like size, some of whichare distinguishable on their obverse or design sides, from the remainingones because of variation in design or coloring or both. On the reversesides of the one type of cards I place the mathematical operations plus,minus, divided by, etc. On the reverse of each of the remaining cards ofthe second type I place one Idigitor fraction thereof. On each side ofthe figure or symbol on each card, I place common-problems utilizingthis particular figure or symbol.

Ordinarily I use one of each symbol cards, and two of each numericalcards up to ten. This gives five symbol cards, plus, minus, divided by,multiplied by and equals. Thus this set would contain twenty-five cards.There is no reason except convenience in playing for so limiting thecards. Thus, two such decks might be shuffled together if more than fivewanted to play.

Assume a game is played among five people, using a set of twenty-fivecards. Then each player is dealt, obverse side showing, one symbol cardand two numerical cards. Then these cards are placed, still with obverseside showing, in a line in front of each player, a symbol card betweentwo numerical cards. The players then turn the cards up simultaneously.There are then, five players with five problems. Each player in rotationsolves his problem. Thus one says five times three is fifteen. Theplayers failing to solve their problems correctly are eliminated andomitted from subsequent dealings. The surviving player wins.

This is but one method of using the cards.

I have added an illustrative embodiment in which I show the obverse andreverse of such cards.

Fig. 1 shows the obverse or design side of one numerical card.

Fig. 2 shows the reverse side with the'large number in the center andthe various figures on each side.

Fig. 3 shows the reverse side with a sy1nbol on it.

Figure 4 shows the obverse side of a symbol card.

Another suggested way of playing the game is to shuie the cards with theobverse sides exposed. Thesymbol cards, being distinguishable, are layedout one behind the other `in a line. In front 4of each symbol card andbehind each symbol card is placed a numerical card. Thus fifteen cardsin all are placed in five rows of three cards. These cards are turnedover exposingl the reverse sides and so presenting such problems as 5X3,3 6, 7+4, 3|5, of which 'we can obviously complete by inspection theanswers 15, *3, 7/4, 8, thus scoring four out of a possible tour points.I have many other ways of scoring and many ways in which the game may-beplayed but this simple illustration is given to explain the principle ofoperation of the cards. Obviously one or more sets .of cards may beused.

Having thus describe-d my invention, what I claim and what I desire tosecure' United States Letters Patent for is:

1. In a game one set of cards containing two varieties of the same sizebut distinguishable on one side each from the other; one variety havingon its reverse side a digit or fraction thereof; the other having on itsreverse symbol.

2. In a game, one set of .cards containing' two varieties of the samesize but distinguishable on one side each from the other; one varietyhaving on its reverse side a digit or fraction thereof; the other havingon its reverse side a mathematical operation symbol; said figure andsymbol on each card being supplement by representative problemsinvolving the said figure and symbol.

In witness whereof I hereunto subscribe my name this tenth day ofJanuary. 1923.
